We all want to be happy, but what does research say about how to become happy? Well, a Harvard study that took more than 75 years has come to one surprising revelation: good relationships keep us happier and healthier.
The Study of Adult Development at the Harvard Medical School, better known as the Grant Study, is considered the longest-running study of human happiness. It was started in 1938 with 268 healthy, male sophomores from Harvard. Over the years, researchers tracked their metal and physical health and as the study evolved, researchers added the children of those men as well as their wives as subjects. According to Harvard, “among the original recruits were eventual President John F. Kennedy and longtime Washington Post editor Ben Bradlee.”
The fourth Grant Study director, Harvard psychologist Robert Waldinger, gave a TED talk about the results. “The clearest message that we get from this 75-year study is this: Good relationships keep us happier and healthier,” Waldinger said. “The people who were the most satisfied in their relationships at age 50 were the healthiest at age 80,” he added.
